Description
- Theory: Voltage Relay
- Power Source: DC
- Model Number: XTW1-0091
- Voltage: 5V
- Usage: General Purpose
use:
Light detection, brightness detection, through the potentiometer can be adjusted to detect the brightness of the valve point, comes with a relay, do a variety of brightness detection switch, you can control a variety of street lights, automatic opening at night, during the day automatically extinguished and vehicle control and automation equipment. (Compared with the photosensitive resistor, the direction is better, you can perceive the fixed direction of the light source, the detection of light in front of the photodiode, the surrounding difficult to detect, often in the search function)
Module Features:
1, the use of photosensitive diode-induced light intensity, comes with a relay, direct control of the load
2, with the potentiometer to adjust the sensitivity, by adjusting the potentiometer, set the starting relay threshold, when the light is on, the module relay pull, hidden in this threshold, the relay release, so then open with the public Side is to control the switch during the day, then closed and the public is the control of the evening switch.
3, the working voltage of 5V
4, the output form: directly AC 220V 10A or DC30V 10A load
5, with four fixed bolt holes, easy to install
6, small board PCB size: 5cm x 2.6cm
7, using a wide voltage LM393 comparator
Electrical parameters:
Supply voltage: 5VDC
Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
Module Instructions:
1, photodiode is most sensitive to ambient light, generally used to detect the brightness of the ambient light.
2, the module in the ambient light exceeds the set threshold, the relay pull, the common side and normally open end, when the ambient light below the set threshold, the relay is off, the common end and normally closed end;
3, the common, normally open, normally closed three ports is equivalent to a dual control switch, the relay coil has electricity, the common and normally open end conduction, no power, the common and normally closed end conduction
